What to Wear in September

The Florida Keys still experience summer weather throughout September. Pack your summer gear, including flip flops, a swim suit, shorts and a light shirt, but be sure to bring light layers that you can add to your wardrobe when needed. If you go boating for example, bring a light jacket. Don't forget protection against the sun.
